Affton Radiator Services

Founded in 1977, Affton Radiator Services has grown from an automotive heating and cooling shop into a leading industrial radiator and cooling system service provider in the St. Louis region. At the beginning of 2026, we proudly expanded our capabilities with the purchase of Glen-Ray Radiators, strengthening our expertise, capacity, and service offerings.

We specialize in servicing large-scale and heavy-duty applications, including semi-trucks, locomotives, marine vessels, and industrial equipment.
